Product Information
Congratulations on your new Ergometer!
The Monark 894 E is an ergometer for anaerobic
tests that also works as a normal traditional weight
ergometer. It has a brake system where the workload
is determined by weights added in the weight basket.
The patented weight basket system does not require
calibration, the precision of the weights ensures that
the workload is correct. RPM-controlled release of
weight basket and test duration up to 99 minutes
increase safety and the potential for optimal tests.
The easy-to-use Windows-based software has more
setting possibilities with clear presentation graphics.
Thanks to double sensors, faster electronics and
improved mechanics, performing anaerobic tests is
now more efficient and less complicated.

NOTE!
Use of the product may involve considerable
physical stress. It is therefore recommended that
people who are not accustomed to cardiovascular
exercise or who do not feel completely healthy,
should consult a physician for advice.

Operating Instruction
Workload adjustment
Through pedalling the test person supplies kinetic
energy to the flywheel. The flywheel is then braked
by means of a brake belt/cord which runs around the
flywheel. The workload is changed either by using
other pedalling speed or by increasing or decreasing
the tension of the brake belt/cord against the flywheel
by place weights in the weight basket. Weights are
available in 1 kg / 2.2 lb, 0,5 kg / 1.1 lb and 0,1 kg
/ 0.2 lb. This makes it possible to vary the workload
from 1 kp up to maximum 11 kp in steps of 0,1 kp.
Braking power is expressed in kp where mass 1 kg /
2.2 lb gives the braking force 1 kp.
NOTE! 1 kg /2.2 lbs is the lowest work load that can
be set as this is the weight of the basket itself. A weight
basket that only weighs 0,5 kg /1.1lb is available as
an option. The weight basket can also be set in its
upper free/resting position and does then not give
any work load at all. The weight basket is released by
pushing the release button(1), on the handlebar. See
Fig: Workload adjustment.
Power measurement
The cycle is designed to measure the power on the
flywheel, because tests/protocols are made for it (for
example Åstrand’s and YMCA).
Cycle adjustments
Seat height should be adjusted to a comfortable
position. The appropriate height is to have the knee
slightly bent when the sole of the foot is centred over
the pedal axle with the pedal in the bottom position.
To adjust the seat height loosen the lever (1) on the
seat tube. See Fig: Adjustments.
The handlebar setting should be in a comfortable
position when cycling. During longer exercise sessions
it is recommended to occasionally change handlebar
position. To adjust the handlebar, loosen the quick
release lever (2). See Fig: Adjustments.
NOTE!
The handlebar stem should be inserted into the frame
tube at least 3 inches (about 8 cm). This measure is
marked with “MAX” on the stem (3).

Anaerobic testing
Model 894 E has a computer for anaerobic testing
and makes the bike possible to connect to an external
PC, PC-cable is included. A Windows application,
included in the bike, makes it possible to make a lot
of different type of anaerobic tests for ex. Wingate
tests and so forth. The anaerobic tests can easily be
set from 5 up to 300 seconds duration. For a closer
explanation of the application look in the program
manual, ”Monark Anaerobic Test Software User
Manual”.
NOTE!
To carry out anaerobic tests must cycle computer
equipped with power from a wall outlet. Connect
the supplied power adaptor into an appropriate
wall outlet (230V). The circular connector on the
secondary cable from the power adaptor is connected
to the corresponding socket on the cycle under
the instrument cover on the right side. PC cable is
connected into the serial port underneath and to a
serial port on an external PC. See Fig: Brake device in
section ”Adjusting the break cord/belt tension”. The
LED (2) on the front of the instrument panel, see fig:
Workload adjustments in section ”Workload device",
indicates both that there is power to the unit and that
the weight basket is in its upper locked position. If the
weight basket produces resistance it must be moved
up in its upper locked position where it does not give
any workload. Then the LED is lit - with a delay of
about five seconds - indicating that the computer and
cycle is in a ready position for a test.
Connection to PC
To connect a PC to the bike, use a 0-modem cable
(RS232) with 9-pin D-sub connector (female) at
both ends. If no RS232 Serial port is available on the
computer use a USB serial converter to connect to an
USB port on the computer instead.
Before installing the Monark Software for your
ergometer, you must take the following steps.
Locate the USB adaptor.1.
Inside the USB adaptor packaging, there is a mini-2.
CD.
Insert the mini-CD into the CD-ROM drive and3.
install the driver software. If there is no CD drive
on your computer, driver software is available for
download from the website (http:www.vscom.de/
USB-CD).
Finalize the driver software installation by4.
inserting the USB adaptor.
Install the Monark Software disk.5.
Connect the USB Adaptor to the Serial Cable and6.
proceed with testing.

Meter instructions
The ergometer is equipped with a Fitness computer
showing pedal revolutions per minute (RPM), heart
rate in bpm (HR), exercise time in minutes and
seconds (TIME), cycling speed in km per hour or
miles per hour (SPEED), covered distance in km or
mile (DISTANCE). Furthermore the workload (kp =
weight basket + weights in kg) can be set which gives
a reading of burned calories (CAL) as well as power
(WATT) on the computer display. The energy is usually
expressed in kJ (kilojoule) or cal (kilocalories, kcal).
One kcal is approx. 4,2 kJ. The power is depending on
the pedalling speed which makes it possible to adjust
the workload/power by increasing or decreasing the
pedalling speed.
When pressing any button, or move the pedals, a
signal gives to the meter that activates all functions.
At the display for heart rate (HR) a heart symbol
is lit which means that the meter is trying to find a
pulse signal from an external source, chestbelt with
electrodes, If the meter cannot find such a signal the
HR function is automatically turned off after 30
seconds. When the function is turned off the heart
symbol is not lit any more. The heart rate function
can be turned on again by pressing a key.
The timer starts automatically when pedals are moved.
Meter values for Time, Distance and Calories can be
set to zero by pressing the RESET button for more
than two seconds.
Display
Pedal revolution (RPM) 0 - 250 rev./min.
HR 50 - 240 bpm
TIME 0:00-99:59 min:sec
SPEED 0 - 99 km/h
DISTANCE 0.0 - 99.9 km
FORCE 0.0 - 7.0 kp
Calories (CAL) 0 - 999 kcal
WATT 0 - 7 x rpm watt
Batteries: 1.5 V x 2, R6 (AA)
Storing temperature: -10º C - +60º C
Operating temperature: 0º C - +50º C
To get correct readings for calories and watts the kp
value on the electronic meter has to be set to the same
value as the workload that is the weight of the basket
including the weights in it. The rubber plates are
included in the calibrated weight of the 1 kg weight
basket.
Example: The workload is 3 kg / 6.6 lbs (weight basket
1 kg / 2.2 lbs + 2 x 1 kg / 1.1 lbs weight). Press the kp
key to the left on the meter. The lower display window
is now flashing and showing figures in kp. Increase or
decrease in steps of 0.1 kp by pressing the kp button
(arrow up) or the RESET button (arrow down)
until the reading is corresponding with the actual or
desired kp values (workload) from the weight basket.
After that press the CAL/WATT button to either
show the CAL or WATT figures. After that press the
CAL/WATT button to either show the CAL or WATT
figures. The watt reading in the display is depending
on the pedalling speed. The watts can accordingly
be adjusted by increasing or decreasing the pedalling
speed. Calories are calculated continuously, more
information in the section "Calories".

Heart rate
A person's heart rate can be measured with a chest
belt that senses the electronic output of the heart. The
chest belt is standard equipment.
Heart rate monitoring requires that the chest belt is
correctly placed. When it is correctly fitted the logo
on the belt will be central and readable, outward
and upright, by another person. Before putting on
the belt, clean the skin where the belt is to be placed.
The chest belt should be secured at a comfortable
tension around the mid section, just below the breast
muscle, see Fig: Placement of the chest belt. Moisten
the electrodes before use, see Fig: Electrodes on the
back of the chest belt. To make contact with the HR
receiver on the bike, the distance should not be more
than 100 cm. It is especially important when first used
to identify the chest belt with the sensor, by standing
close to get the HR (maximum 60 cm).
NOTE!
Electromagnetic waves can interfere with the telemetry
system. Cellular phones are not allowed to be used
near the bike during test.
Fig: Placement of the chest belt
Fig: Electrodes on the back of the chest belt (1)
Calories
There have been different theories on how to calculate
this, since it depends on several factors and this means
that it can only be seen as an estimate.
As a standard calculation when we display calories
on our calibrated bikes we use: 1 minute with 100W
gives 7 kcal. It is easy to convert watts to calories if it
was on the flywheel, the formula is 1W=0,2388x10-3
kcal/s with four decimals. But when you normally
show calories you want to show the total amount of
calories your body has used during your training, not
only the calories "burnt" on the flywheel.
We have chosen the formula given above that we
think complies with the results given for a standard
cycle position.
Km/Miles
Km and km/h is the default setting from the factory.
If you want to make a setting in miles take the meter
out of the panel. Turn off the meter by taking out
one battery. On the back side is a switch(1) with two
settings – 1 and ON. See Fig: Switch km/miles. 1 is
equal to km and km/h and is the default setting. ON
is equal to mile and mph. Choose position and install
the battery again. Put the meter back again into the
panel.
Do not expose the electronic meter to direct sunlight
or extremely high temperature. Do not use any
dissolvents when cleaning. Use only dry cloth.

Adjusting the brake cord/belt tension
1. Check at first that the brake belt is lying correct
on the flywheel brake surface. See Fig: Brake cord
and Brake device. If the weight basket is in its upper
position, press the release button(1). The basket will
fall down and increase the tension of the brake belt/
cord against the flywheel. Put 9 kg in the weight
basket(6). See Fig: Brake device. Rotate the flywheel
by hand. The basket shall now lift up so the distance
to the flywheel is at least 40 mm /1.6" and maximum
60 mm / 2.4". If this is not the case the brake belt has
to be loosened or tightened at the tension centre (4).
If the basket is too low, shorten the belt somewhat. If
the basket is too high, lengthen the cord somewhat.
Tighten the bracket again and check that the distance
between the weight basket and flywheel is between 40
and 60 mm when the flywheel is rotated by hand.
2. Also check the brake cord tension with no load
weight basket. Then check the distance between the
pin on the tension center and the tip of the magnet
arm, as shown in Fig: Brake device This distance
should be between 5 and 10 mm (1/4" and 1/2").
NOTE!
To receive correct workload it is important to place the
weight basket according to the description above.

Check so basket lock sensor and basket drop sensor is working•
properly and also connected to correct ports on bikes circuit board. See
Fig: Connections on circuit board.
Problems with the sensors Technical advice how to check sensors of magnetic type:
1. Unplug the sensor on bikes circuit board.
2. In the jack in the end of sensor cable measure with a summer or an ohm
meter then angle the magnet in near of the sensor. A signal should be heard
or value approx. 0 ohm displayed on ohm meter.
No heart rate Check the chestbelt (battery). Wet the thumbs and place them on the•
electrodes. A low clicking sound will appear near battery lid while you
click on the electrodes with one thumb.
Check that the chest belt is positioned correctly on test person and•
tight enough. Check that the electrodes are wet. In hard cases it is
necessary to use a contact gel or a mixture of water with a few drops
of washing-up liquid. The level for HR signal can vary from person to
person. Put chest belt on another known person who has a good pulse
reading.
Uneven heart rate Use an external unit, for example a HR watch, to check if it also•
indicates an irregular pulse. If this is the case, there is probably
disturbance in the room. Magnetic fields from high voltage cables,
elevators, fluorescent tube etc. can cause the disturbance. Other
electronic equipment could be placed too close. Move the bike to a
different location in the room or change rooms. If an irregular HR
remains it should be checked manually. If the HR remains irregular at
work the person's health should be examined.

Service check and Maintenance
It is important to carry out a regular service on your
ergometer, to ensure it is kept in good condition.
Service action:
We recommend isopropyl alcohol to disinfect the•
surface of the bike. Use a damp but not wet cloth to
clean the surface you wish to disinfect.
Always keep the bike clean and well lubricated•
(once a week).
Periodicallywipethesurface witha rustpreventative,•
especially when it has been cleaned and the surface
is dry. This is done to protect the chrome and
zinc parts as well as the painted parts (4 times per
year).
Check now and then that both pedals are firmly•
tightened. If not the threading in the pedal arms will
be damaged. Also check that pedal arms are firmly
tightened on the crank axle, tighten if necessary.
When the Ergometer is new it is important to tighten
the pedals after 5 hours of pedalling (4 times per
year).
Check that the pedal crank is secure to the crank•
axle (4 times per year).
Be sure that the pedals are moving smoothly, and•
that the pedal axle is clear of dirt and fibres (4 times
per year).
When cleaning and lubricating be sure to check that•
all screws and nuts are properly tightened (twice a
year).
Check that the chain is snug and there is no play in•
the pedal crank (twice a year).
Check that pedals, chain and freewheel sprocket are•
lubricated (twice a year).
Be sure that the brake belt does not show significant•
signs of wear (twice a year).
Check that the handlebars and seat adjustment•
screws are lubricated (2 times per year).
Be sure that all moving parts, crank and flywheel•
are working normally and that no abnormal play
or sound exists. Play in bearings causes fast wearing
and with that follows a highly reduced lifetime.
Check that the flywheel is placed in the center and•
with plane rotation.

Batteries
If the meter is battery-operated, the batteries are in a
separate package at delivery. If the storing time has
been long the battery power can be too low to make
the computer act correctly. Batteries must then be
changed.
Flywheel bearing
The flywheel bearing is long-term greased and requires
no supplementary lubrication. If a problem arises,
please contact your Monark dealer.
Crank bearing
The crank bearing is greased and normally requires
no supplementary lubrication. If a problem arises,
please contact your Monark dealer.
Transportation
During transport the brake cord should be tightened
to prevent it from falling off the flywheel.
Replacement of brake belt
To replace the brake belt remove covers if necessary.
Make sure that the belt is loose.
Alt. 1: To loosen the brake belt on pendulum bikes
with engine, connect power to the unit and raise the
pendulum to 4 kp. Hold it there until brake belt is
loose. Please note how the belt is assembled. Remove
it from the bike. Attach the new brake belt and
assemble the bike in reverse order.
Alt. 2: To loosen the brake cord on cycles with a weight
basket set the basket to its upper position. Loosen the
lock washer that is holding the cord and remove it
from the tension center. Loosen or cut off the knot on
the other end of the cord and then remove the whole
cord from the bike. When assembling a new brake
cord, first enter one end into the hole in the tension
center, and tie a knot and let the knot fall into the
bigger part of the hole. Lock the end of the cord with
the lock washer.
Brake belt contact surface
Deposits of dirt on the brake belt and on the contact
surface may cause the unit to operate unevenly and will
also wear down the brake belt. The contact surface of
the flywheel should be smoothed with fine sandpaper
and any dust removed with a clean dry cloth.
Remove any potential covers and all workload on
the brake belt and then remove it. Grind with a fine
sand paper. Grinding is easier to perform if a second
individual cautiously and carefully pedals the cycle.
Irregularities on the brake belt contact surface are
removed by means of a fine sand paper or an abrasive
cloth. Otherwise unnecessary wear on the brake belt
may occur and the unit can become noisy.
Always keep the brake belt contact surface clean and
dry. No lubricant should be used. We recommend
replacing the brake belt when cleaning the contact
surface. In regard to assembly and adjustment of the
brake belt, see ”Replacement of brake belt”.
Alt. 3: To loosen the brake belt on the bike remove
all tension. Please note how the belt is assembled.
Remove it from the bike. Attach the new brake belt
and assemble the bike in reverse order.
NOTE!
When replacing the brake belt it is recommended
to clean the brake surface. See ”Brake belt contact
surface”.
Monark 894 E 15
Fig: Brake belt contact surface

Chain 1/2“ x 1/8“
Check the lubrication and tension of the chain at
regular intervals. In the middle of its free length the
chain should have a minimum play (3) of 10 mm (1/4
inch). See Fig: Chain adjustments. When the play in
the chain is about 20 mm (3/4 inch) the chain must
be tightened. Otherwise it will cause abnormal wear
of the chain and sprockets. Therefore it is always
recommended to keep the chain play as small as
possible. Loosen the hub nut(2) on both sides and tense
the chain with the chain adjuster(1) when needed.
When the chain has become so long that it can no
longer be tightened with the chain adjusters it is worn
out and shall be replaced with a new one.
To adjust or replace the chain, remove covers if
required.
To adjust the chain the hub nuts (2) should be
loosened. Loosening or tightening the nuts on the
chain adjusters (1) will then move the hub and axle
forward or backward. Then tighten the nuts on the
hub axle again. See Fig: Chain adjustments.
To replace the chain, loosenthe chain adjusters as much
as possible. Dismantle the chain lock (6) and remove
the chain. Use a pair of tongs for dismantling spring.
Put on a new chain and assemble the chain lock. The
spring of the chain lock should be assembled with the
closed end in the movement direction(5) of the chain.
Use a pair of tongs for dismantling and assembling
the spring (4). See Fig: Chain replacement.
NOTE! At assembly the flywheel has to be parallell
with the centerline of the frame. Otherwise the chain
and sprockets make a lot of noise and wear out rapidly.
Then assemble the removed parts as above but in
reverse order.

Freewheel sprocket
When replacing the freewheel sprocket remove frame
covers if necessary. Remove the chain according to
section ”Chain 1/2” x 1/8””.
Loosen the axle nuts and lift off the flywheel. Remove
the axle nut, washer, chain adjuster and spacer on
the freewheel side. Replace sprocket-adaptor and
assemble the new parts in reverse order according to
the above.
NOTE! Do not tighten the axle nut completely. It
must be possible to loosen the sprocket-adaptor half
a turn.
The sprocket should be lubricated with a few drops of
oil once a year. Tilt the cycle to make it easier for the
oil to reach the bearing. See Fig: Lubrication.
